Experimental investigation of charge-exchange processes involving a target proton in (16)Op collisions at a momentum of 3.25 GeV/c per nucleon

摘要

For the first time, charge-exchange processes involving a target proton in (16)Op collisions at a momentum of 3.25 GeV/c per nucleon are studied under conditions of 4 pi geometry. New data on the mean multiplicities fragments and pions, as well as on inelastic cross sections for topological channels of the fragmentation of an oxygen nucleus in charge-exchange reactions involving a target proton that either are accompanied or are not accompanied by charge transfer to a projectile nucleus, are presented. It is shown that, in (16)Op interactions at high energies, charge transfer from a target proton to a projectile nucleus proceeds predominantly via inelastic proton scattering on a neutron of the oxygen nucleus.
